It‘s curious that le Carré started off his series about a spy with two murder mysteries, or rather he wrote the final 7 books of his murder mystery series about spies. Regardless, the buildup was great, but the ending was rushed and the motive for the killer—in my opinion—was quite thin and vague. It is an odd leap from this George Smiley novel into the next one. ⭐️⭐️⭐️/5
